,WINDMIL'L.

Toall whom it may concern: I

Be it known that I, ERNST AUcUs'r To- -BORG, a citizen of the United States, residing at Biggs, in the county of Butte and State of California, have invented new and useful Improvements in Windmills, of which the following is a specification.

My present invention hasreference to an improved construction in wind mills.

In carrying out my invention, it is my purpose to produce a'wind mill with a wheel of a particular and peculiar construction whereby the vanes thereof will be in'a position'to receive the wind, regardless of the direction of the wind, and wherein the wheel isat all times automatically controlled when in'motionand locked against motion when not required for pumping or other purposes.

It is also my purpose to produce a wind mill in which the wheel thereof is made up of spaced vertically disposed cross sectionally concavo-convex blades or vanes connectedtogether by peripheral'bands, the in-' ner bands having radially directed spokes le'adin-g to hubson which the shaft for the wheel is secured, a revoluble' element normally in thepath of'engagementwith one of theouter-bands of the wheel, and a-governor actuated by the shaft for controlling the frictional engagement of the revoluble -member'with respect to the band adjacent thereto, whereby the revolution of the wheel I and the speed of the shaft is governed, while in addition to this, manuallyoperable means is'also provided for forcing the revoluble element against the band and locking the wheel and shaft from turning, when the mill is not desired for use. p a V V The foregoing, and'm'any' other objects which will appear as the nature of the 'invention is :better understood, may be accomplished by a construction,combination and operative association of parts, such as is 'disclosedby the drawings which accompany and-which form part of this specification.

The frame of my improvedwind mill is preferably constructed of angle irons, in-

cluding cornerposts 1, cross members 2 con- .necting the corner posts, and brace means between the lower series of cross pieces 2 and corner posts. The braces 3, at the'top of the frame are reinforced by curved brace members 4 and straight right angularly disposed brace members The cross pieces 2, next to thetop cross pieces are reinforcedby horizontal angularly arranged braces 6, and also there is secured centrally between two of the 0pposed cross pieces 2 a flat plate 7. The plate -vided with spaced hubs 9 and '10 respectively. Both the hubs haveradiating spokes 14 respectively to which are secured ring members or bands 15 respectively. Th'

bands 15 are p'referably made-up of vments, the ends of which being flanged against the spokes and-bolted thereto, "asat 17. Thusthe ends of the spokes project a determined distance beyond the'bands 1'5,

Iand have fth'eiriouter ends offset or flanged, as at 18 and connected by bolts or "the like to outer bands 19 respectively. Disposed between the upper and lower-spaced inner and outer pairs of bands are theva nes '20 for the wheel. Eachoffthe vanes is preferably const'ru'cted from a single plate of metal or other light material which: is rounded longitudinally upon itself so that each vaneis concave-convex in cross section: Thegedgesof theyanes '20 at the top and bottom portions thereof are in frictional engagement with the respective inner and ou'terbandsfor the spokes of the wheel, and passing through the said edges of the vanes andthrough the respective bands of the upper and lowerspoke members are bolts or rods 21;. The elements 21mat'erially reinforce thevanes 'atthe portions thereof which afreconneeted "to "the spaced flange, and in a like manner hold the on. two opposed cross members 2, at "the said bandsin'properspaced i-relation toeaeh othergj v term a platform and which is indicated by the numeral 22. The platform is centrally reinforced by upright'posts 23 that are secured to the base 24 on which the frame rests. The platform is provided with a bear: ing 25 for the lower end of the shaft, and the'said shaft, above its bearing has keyed thereon a beveled pinion 27 This pinion is in mesh with a similar pinion 28 which has its shaft'29 journaled in bearings 30 on the platform and disposed laterally with respect to the platform." On the end of the shaft which projects beyond the platform there is a wheel 31. 1 To this wheel there is eccentrically pivotally connected, as at 32, a pitman 33, which has its lower end loosely connected to the plunger rod for a pump 36. The turning of the wind wheel will, through the means just described, reciprocate the pump rod. Arranged diagonally" between one of thecorner posts and the platform 22 is an auxiliary frame which includes a base 37 provided on its inner end with an up-' standing lug 39 that has a web portion connecting the same to the post 38. The post 38, at its upper end is connected to one of the corner posts 1 of the main frame by a bar or plate 40, the same being secured to one of the horizontal braces between the.

cross pieces 2 at the base or bottom of the wind wheel. Th plate 40 and thebase 37 of the auxiliary frame have elongated slots therethrough through which passes an arm 41. This arm is pivoted, as at 42 tothe plate 40, and projects a suitable distance below the base plate 37, having its outer end received in a slotted guide 42' that is supported from the base 24 of the frame and on of the corner posts of the said frame. The-arm 41, at its upper end and'on its inner face carries a roller 43 which is disposed opposite and in the path of contact with the outer lower band of the wind wheel. 1 The roller has its shaft journaled in a suitable bracket 44 on the inner dge of the lever.

, Thelug 39 isbifurcated and has pivoted therein thelonger arm 4501: an angle lever.

-The'short'erarm 46 ofthe angle lever has its end provided with an eye 47 through which passes a bail-like member 48 that is secured on the inner edge of the arm 41. The arm 47 has its outer-end provided with an elongated slot 49 thatreceives therea through a pivoted pin 50 provided on the 55..

angle end-'51 of. a lever 52. The lever-52 is pivoted, as at 53 in a slot adjacent to the upperend of thepost 38, and has its outer end formed with a sleeve 'or collar 54 that surrounfdsthe, shaft 8 and which is contacted by a, disk-55 that forms the head "member vofa-governors; The disk has on its lower face 7' opposed downwardly directed i-ears 56-towhich-arepivoted armsl57. The

'armss57 have their lower ends bifurcated I and jarepivoted, as at 58 .to .arms 59 that 62 that is keyed or otherwise secured to the shaft 8. It will be apparent that the turnin of the wind wheel and its shaft will swing the weighted arms of the governor, causing the arms or links that are connected to the disks to elevate the said disk and in so doing swing the angle'lever on its pivotal connection with the post and the angle lever which is pivotally. supportedon the lug, causing the latter to influence the arm 41 to bring the roller 43 into frictional engagement with the outer lower band of the wind wheel, and thus regulate the turn ing of the wind wheel and shaft; By employing the pivoted roller 43, as a braking means, in lieu of an ordinary brakeshoe, a

more gentle braking action is afforded. It is not desirable that the wind wheel be broughtto an abrupt stop as such might result in the breakage ofcp arts, and the friction of the vanescof the wheelis such that the wheel will be revolublei regardlessiof the direction of the wind abutting-thereagainst,

and it is thought that'the foregoing descrlption, when taken in connection with the drawings will amply set "forth the construction, operation and advantages of the improvement. It is believed necessary to state, however, that the nature of the'invention is such as to render the'same susceptible to various changes and- IDOdIfiGatIOIIS WhICh fall within the scopeof what is claimed and that I am thereforeentitled I to make such changes.

' Having" described thein v entioin g' I claim:-. V.

v1. A wind wheel "having a :peripheral band, a shaft. forthe-wheel, apivotallysupported arm, aroller carried thereby the path ofjenga'gement with the band, and

means between the shaft and arm, actuated" by the rotation of the shaft for swinging the arm to bring the roller into or out of frictional engagement with the baind,:-in accordance with the speed of rotation of the shaft and wheel, and means, independent of said a shaft operating means for locking thelever in a position to causetheJrollent'o engage "the band with" sufiicientfriction to *prevent the turning'of the wheel and' 'sha ffl 2. In' a :wind: wheel,- a; frame, a vertically disposed shaft journaledij therein,-.cspaced vbetween the inner and outer bands, elements passing through the bands and plates holding the plates between the bands and spacing the bands, friction means in the path of contact with one of the outer bands, and means actuated by the turning of the wheel and shaft for regulating the engagement of the friction means with the said band.

3. in a Wind mill, a frame, a shaft journaled vertically and centrally therein, a wind wheel secured to the shaft and comprising cross sectionally rounded vertically disposed vanes disposed between inner and outer bands, spokes radiating from the shaft and connecting the inner and outer bands, a pivot-ally supported arm, a roller journaled in bearings at the upper end thereof,

and in the path of contact with one of the bands of the wind wheel, a governor including an element which is slidable on the shaft, a pivotally supported angle lever having a collar surroun ing the shaft and in the path of contact with the slidable element of the governor, a second pivotally supported angle lever loosely connected to the first mentioned angle lever, a loose connection between the last mentioned lever and the arm whereby when the first mentioned lever is influenced by the governor the last mentioned lever will swing the arm to bring the roller carried thereby in frictional. engagement with the band of the wind wheel, guide means for the lower end of the arm, and means carried by said guide means forlocking the arm thereto and holding the roller in suflicient frictional engagement with the band to prevent the turning of the wheel and shaft.

In testimony whereof I affix my signature.
